I don't understand the crazy first week predictions people are making.
Uncharted isn't a newish franchise for sales to randomly explode. Last of Us 2 I can defenitely see doing significantly better than the first one. Uncharted has stayed fairly consistant over its past two iterations and I doubt things will change much on the PS4. The ps4 is selling more than the ps3 but Uncharted 3 launched to a much more massive installbase and did nowhere near those numbers.
1.5-2mil first week
7-9mil lifetime depending on how hard they go on the bundling.
